Thank you very much for helping me understand better the process of aligning images. I agree with you that this particular 3view is nou accurate enough and I will look for a better one
Hi Bill,
is that a Gulfstream G500/G550? Otherwise I converted( to PDF via Photoline) and imported the SVG-file from this Wikipedia article https://en.wikipedia.org/wiki/Gulfstream_G550#Specifications. These are actually all unconnected curves, no tracing necessary. I grouped the curves and named them after their initial view, so front, side and top. Might be of some help, i dunno.
Thank you very much for your input. I found it very interesting. I am not sure that I no what an SVG file, or how you obtained it, but your geometry matches much better than the 3 view that I had.
